AMALGAMATOR.

Specification of Letters Patent.

Patented Feb. 27, 1912.

Application filed April 23, 1910. Serial No. 557,158.

To all whom it may concern:

Be it known that I, JAMES G. Scorr, a citizen of the United States,residing at Morgantown, in the county of Morgan and State of Indiana,have invented a new and useful Amalgamator, of which the following is aspecification.

The object of my invention is to produce an amalgamator by means ofwhich precious metals may be separated from their carrying sands.

The accompanying drawings illustrate my invention.

Figure 1 is a plan of a water machine embodying my invention; Fig. 2 asection of the machine shown in Fig. 1; Fig. 3 a plan of an air-blastmachine, and Fig. 4 a section of the structure shown in Fig. 3.

In the drawings, 10 indicates a suitable supporting frame carryingadjustable pins 11, 11 between which is journaled a shaft 12 carrying arotary amalgamating disk 13 the working face of which is serrated, in anordinary manner, as indicated at 14. It will be understood that thepresent drawings very greatly exaggerate the depth of the serrations 14.The disk 13 is circular and surrounding said disk, so as to form avertical wall therefor, is a belt 15 of any suitable material such, forinstance, as ordinary leather belting. The belt 15 closely engages thecircumference of disk 13 throughout the major portion thereof but at onepoint is drawn away from the circumference of the disk and passed over asuitable idler 16 so as to thus form an opening 17 through which thesands and the carrying current of water or air may escape. Disk 13 isslightly higher at its edges than at its middle, as indicated in Fig. 2so that the disk is slightly dished andat its center is provided with ahub 18. The disk 13 is rotated in any suitable manner as, for instance,by means of a gear 19 and a pinion 20 carried by shaft 21.

Mounted above disk 13 and coming down fairly close to its upper face areseveral baffle-plates 22 which serve to produce eddies in thesand-carrying fluid. Arranged above the disk and extending diagonallyacross the same from the circumference to hub 18 are two flexible dams23 and 24. The dam 24 is serrated at its bottom so as to fit within theserrations of the table 13, while dam 23 is brought practically to thecrests of the ridges of the table. The two rested by it to move towardthe center of I the table. Immediately adjacent the inner end of the damand the circumference of hub 18 is a pump 26 the suction end 27 of whichis broadened and brought close to the working face of the table. Thepiston rod 28 of the pump is connected in any suitable manner as bylever 29 and pitman 31 with a crank 32 carried by shaft 21. The dams arecarried by suitable adjusting screws 33 by means of which they may beadjusted toward and from the working face of the table. In the formshown in Figs. 1 and 2 a water pipe 35 is led to a point above the tablein advance of dam 27 so as to direct a stream of water onto the table inthe direction of rotation thereof and the water pipe 36 is provided todirect a stream of water in the opposite direction at a point justbeyond the opening 17 so as to thus facilitate the outflow of water andsands carried thereby.

The structure shown in Figs. 3 and 4 is substantially identical withthat already described except that I provide a cover plate 41 which liesimmediately above the upper edge of belt 15 so as to form a reasonablyair-tight cover for the table. An opening 42 is provided in this plateimmediately in front of dam 23 and in front of this open ing anair-blast nozzle 43 leads into the space above the table.

In operation, a suitable supply of mercury is placed within the chamber25 and the table 13 rotated in the direction indicated by the arrow. Themetal bearing sands are then introduced on to the table in front of dam23 and streams of water or air introduced on to the table. The sanddisturbing fluid will be obstructed by the deflectors 22 and the metalbearing sands will be thus intermittingly agitated and allowed to settleso that the precious metals may fall into the mercury which passes outfrom chamber 25 under dam 23. When the material reaches the opening 17the belt 15 will move away from the circumference of the table as topermit the egress, while the amalgam will pass to dam 24 by which itwill be caused to flow toward the center of the table to pump 26 and thesaid pump will Withdraw the amalgam from table and di'icharge it throughthe discharge pipe 51 H any desired point.

I claim as my invention:

1. In an amalgamator, the combination o a rotary table, means forsupplying amalgamating material thereto, means for rotating said table,a belt engaging the circumference of said table to form a Wall therefor,a support over Which portions of the belt will be successively carriedas the table rotates, said support lying beyond the circumference of thetable, a dam arranged to cooperate with said table to cause a movementof the amalgain transversely of the table, and a pump arranged above thetable in position to receiVe the amalgam displaced by the dam.

2. In an amalgamator, the combination of a rotary table, means forsupplying amalgamating material thereto, means for rotating said table,a belt engaging the circumference of said table to form a Wall therefor,a support over Which portions of the belt Will be successively carriedas the table rotates, said support lying beyond the circumference of thetable, and a dam arranged to cooperate with said table to cause amovement of the amalgam transversely of the table.

In witness whereof, 1, JAMES G. Soo'r'r have hereunto set my hand andseal at MorgantoWn, Morgan county, Indiana, this 18th day of April, A.D. one thousand nine hundred and ten.
